Question

Cần gấp

Answer 1

1: \(\left(x^3y^3-\frac12x^2y^3-x^3y^2\right):\frac13x^2y^2\)

\(=x^3y^3:\frac13x^2y^2-\frac12x^2y^3:\frac13x^2y^2-x^3y^2:\frac13x^2y^2\)

\(=3xy-\frac32y-3x\)

2: \(\left(\frac23x^3y^2-x^2y+6x^3\right):\left(-\frac14x^2\right)\)

\(=-\frac23x^3y^2:\frac14x^2+x^2y:\frac14x^2-6x^3:\frac14x^2\)

\(=-\frac83xy^2+4y-24x\)
